Abstract
The invention concerns an electrode wire comprising a metal core (16) coated with a zinc surface cladding (17) whereof the thickness (E) ranges between 2 and 4 μm, thereby providing a better compromise between machining speed, precision of workpieces and surface condition of the machined workpieces.
Claims8
An electrode wire for spark erosion machining comprising a metal core (16) coated with a surface layer (17) of zinc, characterized in that the thickness (E) of the surface layer (17) of zinc is from approximately 2 μm to approximately 4 μm.
